There is a single *PDP_STATUS* message on this API. PDPs send this message to the PAP using the -*POLICY_PDP_PAP* DMaaP topic. The PAP listens on this topic for messages. - -When a PDP starts, it commences periodic sending of *PDP_STATUS* messages on DMaaP. The PAP receives these messages and -acts in whatever manner is appropriate. *PDP_UPDATE*, *PDP_STATE_CHANGE*, and *PDP_HEALTH_CHECK* operations trigger a -*PDP_STATUS* message as a response. - -The *PDP_STATUS* message is used for PDP heartbeat monitoring. A PDP sends a *PDP_STATUS* message with a state of -*TERMINATED* when it terminates normally. If a *PDP_STATUS* message is not received from a PDP periodically or in -response to a pdp_update, pdp-state_change, or pdp_health_check message in a certain configurable time, then the PAP -assumes the PDP has failed. - -A PDP may be preconfigured with its PDP group, PDP subgroup, and policies. If the PDP group, subgroup, or any policy -sent to the PAP in a *PDP_STATUS* message is unknown to the PAP, the PAP locks the PDP in state PASSIVE. - -.. code-block:: yaml - :caption: PDP_STATUS message from an XACML PDP running control loop policies -

It also -allows the PAP to order health checks to run on PDPs. The PAP sends *PDP_UPDATE*, *PDP_STATE_CHANGE*, and -*PDP_HEALTH_CHECK* messages to PDPs using the *POLICY_PAP_PDP* DMaaP topic. PDPs listen on this topic for messages. - -The PAP can set the scope of *PDP_STATE_CHANGE* and *PDP_HEALTH_CHECK* messages: - -- PDP Group: If a PDP group is specified in a message, then the PDPs in that PDP group respond to the message and all - other PDPs ignore it. - -- PDP Group and subgroup: If a PDP group and subgroup are specified in a message, then only the PDPs of that subgroup - in the PDP group respond to the message and all other PDPs ignore it. - -- Single PDP: If the name of a PDP is specified in a message, then only that PDP responds to the message and all other - PDPs ignore it. - -Note: *PDP_UPDATE* messages must be issued individually to PDPs because the *PDP_UPDATE* operation can change the PDP -group to which a PDP belongs. - -2.1 PDP Update --------------- - -The *PDP_UPDATE* operation allows the PAP to modify the PDP group to which a PDP belongs and the policies in a PDP. - -The following examples illustrate how the operation is used. - -.. code-block:: yaml - :caption: PDP_UPDATE message to upgrade XACML PDP control loop policies to version 1.0.1 - :linenos: - - pdp_update: - name: xacml_1 - pdp_type: xacml - description: XACML PDP running control loop policies, Upgraded - pdp_group: onap.pdpgroup.controlloop.operational - pdp_subgroup: xacml - policies: - - onap.policies.controlloop.guard.frequencylimiter.EastRegion: - policy_type: onap.policies.controlloop.guard.FrequencyLimiter - policy_type_version: 1.0.1 - properties: - # Omitted for brevity - - onap.policies.controlloop.guard.blackList.EastRegion: - policy_type: onap.policies.controlloop.guard.BlackList - policy_type_version: 1.0.1 - properties: - # Omitted for brevity - - onap.policies.controlloop.guard.minmax.EastRegion: - policy_type: onap.policies.controlloop.guard.MinMax - policy_type_version: 1.0.1 - properties: - # Omitted for brevity - -.. code-block:: yaml - :caption: PDP_UPDATE message to a Drools PDP to add an extra control loop policy - :linenos: - - pdp_update: - name: drools_2 - pdp_type: drools - description: Drools PDP running control loop policies, extra policy added - pdp_group: onap.pdpgroup.controlloop.operational - pdp_subgroup: drools - policies: - - onap.controllloop.operational.drools.vcpe.EastRegion: - policy_type: onap.controllloop.operational.drools.vCPE - policy_type_version: 1.0.0 - properties: - # Omitted for brevity - - onap.controllloop.operational.drools.vfw.EastRegion: - policy_type: onap.controllloop.operational.drools.vFW - policy_type_version: 1.0.0 - properties: - # Omitted for brevity - - onap.controllloop.operational.drools.vfw.WestRegion: - policy_type: onap.controllloop.operational.drools.vFW - policy_type_version: 1.0.0 - properties: - # Omitted for brevity - -.. code-block:: yaml - :caption: PDP_UPDATE message to an APEX PDP to remove a control loop policy - :linenos: - - pdp_update: - name: apex_3 - pdp_type: apex - description: APEX PDP updated to remove a control loop policy - pdp_group: onap.pdpgroup.controlloop.operational - pdp_subgroup: apex - policies: - - onap.controllloop.operational.apex.bbs.EastRegion: - policy_type: onap.controllloop.operational.apex.BBS - policy_type_version: 1.0.0 - properties: - # Omitted for brevity - -2.2 PDP State Change --------------------- - -The *PDP_STATE_CHANGE* operation allows the PAP to order state changes on PDPs in PDP groups and subgroups.
